Fig. 6From: Effect of an enteral amino acid blend on muscle and gut functionality in critically ill patients: a proof-of-concept randomized controlled trialAlkaline phosphatase (UI/L) in the amino acid and placebo groups. Alkaline phosphatase concentration was assessed by spectrophotometry. Values reported are mean changes from baseline at days 7, 14, 21 and 60, using a restricted maximum likelihood (REML)-based repeated measures approach.
